Original application filed March 2, 1.910, Serial No. 546,899. Divided.and this application filed February To all whom it may concern:

Be it known that l, Jon IIITTGHINSON, a citizen of the United States,residing at New York, in the county of Queens and State of New York,have invented new and useful Improvements in Changeable Indicators, ofwhich the following is a specification. I

My invention relates to changeable indi caters, in general, and moreparticularly to train departure indicators for railway depots, being adivisional application of that filed by me March 2, 1910, Serial No.546.899, the present application being drawn to the specific structureof the means for indicat ing the time of departure of trains, thegeneral support and the means for showing the names of the trainsforming the subjectmatter of the parent application referred to.

The objects of the present invention are to provide a selfcontainedinstrument which will indicate the time of departureof a thin from anydirection in which the indicator may be viewed; to improve theconstruction of the time-indicating and operating mechanism, and toimprove the details of construction of these machines.

In carrying the invention into effect I provide a standard of sutiicientheight to carry the train-name and the time indications the FY0136?distance above the ground, and all, operating connections are arrangednear the base of the standard where they may be readily reached andmanipulated by a person standing on the ground. An indicator havingfourfaces is shown, although a greater or less number of faces may beprovided if desired or found expedient, and the time indication ischanged simultaneously and correspondingly upon each of said. faces.

The IlIlVGllllOll consists in the novel combinations of parts andfeatures of construc tion hereinafter described and claimed and shown inthe accompanying drawings, in which- Figure 1 a front view. inelevation, of the indicator complete; Fig". 2 is a crossseetional viewtaken on lines 22 of Fig. 1; Fig. 3 is an enlarged side view of the timeweb mechanism, the casing for the same having been removed; Fig. t is aplan view of the same; Fin. 5 is a detail of the reels for the timewebs; Fig. 6 is a. detail of the sprocket adjustment of certain of thetime reels; Fig. 7 is a detail view of a modified Serial No. 749,652.

form of frame, showing a different arrangement for pern'iitting readyremoval of the reels.

In F ig. l of the drawings I have shown the complete structure asdisclosed in the parent application, A designating the indi catingportion, and B the train-name portion, both mounted on standard C, whichlatter maybe of any desired height. The indicator illustrated has fourfaces upon each of which the same indication appears. The presentapplication being drawn to the time-indicating portion A, the detaileddescription is more particularly confined to the disclosure of thatportion. Thetime indicating portion A comprises a plurality of sets ofwebs a, a, 0", c which are mounted on suitable reels. As the webs and.reels of each set are similar, a description of one set, (1., forinstance, will sutlice for all. Web a, which carries only the numeral 1,need only be short and is shown as an endless web passing around. reel 1and the idlers on the face of the indicator. lVcbs a, 0/, and (6 arelonger and are mounted on pairs of reels. The outer reel (1. is mountedin frame a, which frame is bolted or otherwise secured to the main frameThe operating reel a of this pair is mounted on frame (4 and isoperatively geared to reel (4 by sprocket chain a engaging sprockets onthe spindles of these reels. The other pairs of reels, for webs a and care similarly mounted and connected. Reel 1. has a driving sprocket l,mounted in the same plane and on an extension of the spindle of saidreel as the corresponding sprocket of the other sets, 6, 0 and (Z, andin this same plane is a driving sprocket 1 mounted on shaft 1 whichextends downwardly through the standard and is operated by a crankthrough opening 1 in the casing. A sprocket chain passingaround saidsprocket wheels 1 of each set a, 7), a, (Z, and also over sprocket 1',constituting a driving; connection. Corresponding sprockets 2 of eachset are also arranged in a common plane with drive sprocket 2, and theseconnected by a sprocket chain in a manner similar to that justdescribed. The same is true of sprockets 3 and 4 of each set. Sprockets2, 3 and l: are provided with a. special adjustable clamping; device forattachment to their respective spindles, as shown in Fig. 6, where itwill be seen that a block 21, secured to or forming part of the sprocketwheel, is drilledto receive a key 22, notched at 23, and capable ofbeing drawn tight. by nut 24. By this means the time webs or bands maybe brought to the proper positions initiallv and then the sprocket wheelclamped to the spindle in the adjusted position.

A preferred construction of the time reels is shown in Fig. 5, where itwill be seen that the reel is formed in two longitudinal portions 30,each having a rib 31 channeled at 32 to fit the spindle. These portionsare secured together and to said spindle by screws 33. The end of theweb is attached at 34.

In Fig. 7 I have shown the frames, as for instance a", of a slightlymodified construction, the members carrying the idlers on the face ofthe indicator, these members being divided longitudinally into twoparts, the line of division intersecting the axes of these idlers, theouter part being removably secured to the other part, thus enabling theidlers to be readily removed by simply disengaging the outer part orsection of the members. This removal of the idlers enables ready accessto be had to the reels, when such access is desired for purpose ofrepairing webs, etc.

hile I have described various embodiments and details as illustrative ofmy invention, I do not wish to be limited specifically to the exactcombination and various details set forth, as I am aware thatmodifications and changes may be made, or some of the features usedeither alone or in other combinations, without departing from the spiritof the invention, and all such changes I aim to cover by and within thescope of the appended claims.

Having thus described my invention, what I claim as new, is:

1. A changeable indicator comprising a main frame, an auxiliary framefor and carried by each face of the main frame, a set of flexible websfor each of the faces of the main frame, a pair of cooperating reels foreach web, one reel of each pair being carried by the main frame with theother reel carried by the auxiliary frame, the inclividuals of each pairbeing geared together, a plurality of drive shafts, and a drivingconnection bet-ween each shaft and corresponding individual reels ineach set.

2. A changeable indicator comprising a set of indicating means for eachof a plurality of faces thereof, an operating .drum for each saidindicating means, a gear wheel for each drum, the gear wheels ofcorresponding drums in each set being substan tially inthe same planewith each other and in a different plane from other gear wheels, aplurality of drive shafts, a drive gear on each shaft in the plane ofcorresponding gear wheels, and a flexible connection between each drivegear and the gear wheels of the corresponding drums.

3. A changeable indicator comprising a plurality of indicating means foreach face thereof, a main frame, an auxiliary frame for each facesecured to the main frame, and operating means mounted on the main frameand geared to said indicating means.

4. A changeable indicator comprising a set of flexible webs for each ofa plurality of faces thereof, a main frame, an auxiliary frame for eachface secured to the main frame, a reel for each web mounted on saidauxiliary frame, an operating reel for each web mounted on the mainframe and geared to its cooperating reel, and driving connections forsaid operating reels.

5. A changeable indicator comprising a main frame, an auxiliary frame, aset of flexible webs adapted to combinedly expose an indication on aface of the auxiliary frame of the indicator, the indication beingformed of individual indications carried by the webs individually,independent supporting elements for the webs, each element in cluding areel operable at will and positioned in rear of the indicating face,said frames combinedly carrying said elements, and idlers carried by theauxiliary frame for controlling the path of travel of the webs to placethem in exposing position.

6. A changeable indicator comprising a main frame, an auxiliary frame, aset of flexible webs adapted to combinedly expose an indication on aface of the auxiliary frame of the indicator, the indication beingformed of individual indications carried by the webs individually,independent supporting elements for the webs, each element including areel operable at will and posi tioned in rear of the indicating face,said frames combinedly carrying said elements, idlers carried by theauxiliary frame for controlling the path of travel of the webs to placethem in expo-sing position, said auxiliary frame being divided on a lineintersecting the axes of the idlers to permit removal of the latterwithout affecting the normal position of the remainder of the frame.

In testimony whereof I- have hereunto set my hand in presence of twosubscribing witnesses.
